Some great shots.
I like that '62 Pontiac 4 dr. HT and the Firebird with the SOHC inline six, not a common engine for the Firebird.
I'm Canadian, but I do recall '50's and '60's Pontiacs very well. Both kinds...American Pontiacs and Canadian Pontiacs.
The 'American' Pontiacs as we used to call them in Canada, had Pontiac drivetrains..the Pontiac V8.
However, through the '50's and '60's the Canadian market Pontiacs we got up here, were Pontiac bodies on Chevy frames with Chevy drivetrains. That would be everything from the inline GMC six (261) and smaller Chevy six, the small block V8 (265,283,327, 350) , the W series big blocks (348, 409) and the Rat motor BB V8's...396, 402, 427, 454. We called the Canadian market Pontiac- Chevies...'Canadian' Pontiacs.
Growing up I spent my summers (2 months a year) in Northern Minnesota for a number of years, and of course in Minnestoa and North Dakota, saw the 'American' Pontiacs with the Pontiac V8 engines..287, 317, 326, 371, 389, 400, 421, 428 throughout the '50's/'60's.
The car bodies were pretty well the same, but the model names were different and the Canadian Pontiacs did not have the U.S. Pontiac wide track, rear axle.
I don't know why GM did this, but it made for some interesting combinations.
Thank you for posting your photos. The '62 'American'
Pontiac triggered some pleasant memories of Pontiac cars on both sides of the border, of the '50's and '60's for me.
